Apple's goal with 2017 MacBook was to do the impossible: engineer a full-size experience into the thinnest, lightest Mac notebook yet. And not only is it compact — it’s more powerful than ever. The new MacBook delivers up to 20 percent faster performance with new seventh-generation Intel Core m3, i5, and i7 processors, and up to 50 percent faster SSD storage.

With powerful technologies in an incredibly compact enclosure, the MacBook is designed to fit perfectly into a world where just about anything you do with a notebook can be done over the air. For those moments when you do need to plug in, USB-C packs a ton of capability into one small and convenient port.
